This is the second post on my power supply build – also see part I and the Circuitmaker project page. The aim of this project is to design and build a linear bench power supply with adjustable current and voltage and up to 2.5A output from 0-30V.
After building and testing the first version of the board I discovered a couple of issues. Most of the basic functionality worked – the voltage control, digital display, transformer tap select, etc. However, the current limiting never worked properly, there were some noise/oscillation issues and a couple of mechanical problems. So, Rev.1.1 was born which has now been tested and seems to be working nicely.
